    Make sure the flame is hitting the thermocouple. If it is and you are still experiencing shut down, inspect the connection at the gas valve. Make sure it is not cross threaded. If you have done all this and still no flame, you are looking at replacing the gas valve.



    If you have a good multimeter that measures Millivolts, connect one lead of the meter to the thermocouple and the other to ground. You are looking for between 500 and 750 millivolts when you apply a flame to the end. This will tell you if the thermocouple is good or not.

Real odd one as if ignition fails this unit is designed to flash various lights to give you an idea of what the fault is. Also this usually happens after about 10-15 seconds. I'm going to have to ask you to clarify that no other lights flash. If I had this fault exactly as you descibe, after running some basic tests to check gas supply and any obvious damage or burnt out components I would change the the main PCB as a start and the control PCB as a plan B.

not a problem. however, if you want to shrink it down... it's hard to say just what your gas valve is like. There should be 2 spots on it for adjustments, the larger slot (should be covered by a brass plug) adjusts the main burner output, the smaller adjusts pilot output. crank it down and watch the pilot shrink, but in this situation bigger is better. the pilot creates an electrical signal that opens the gas valve, you don't want that signal to be too weak.
It would be wise to clean the pilot supply, to have a cleaner flame. pressurized air does well with out having to remove it.

When I try to use my Thermolaire model SU402E, the pilot lights( and stays lit), but the main burner will NOT ignite.. any suggestions as to what could cause this if the pilot stays lit?


Bad igniter? When you 1st try it the gas valve will give enough gas that you would get the burner lit if the igniter was glowing red. If you're desperate you can light the igniter area w/ an aim n flame, but you definitely want to do that w/ caution and crank up your t-stat so the furnace stays on awhile Cuz you'll have to do it again for heat or buy an igniter($40 or so)

I changed the thermo coupler and the pilot light does stay lit but the burners won't light


If you are referring to a gas fireplace:

  • Make sure the pilot knob is turned from "pilot" to "ON" or it will never run.
  • If the pilot knob is "ON", and the pilot is lit, but the burner won't light, it could be a bad Thermopile. The thermopile is the other safety mechanism in the pilot assembly that controls the burner.

I have a readyheater model 65-85 the flame will not stay lit im thinking thermal couple is there a way to test this part? or could it be another problem?


If your pilot light will not stay lit when you release pilot light button then chances are that your thermocouple is bad. Make sure that the tip of thermocouple is directly in line with pilot light. Tip of thermocouple should be cherry red if it is properly placed. If pilot will not stay lit then replace it. If you aren't sure about placement of thermocouple you can heat thermocouple with a seperate heat source. If you do this and pilot light stays lit then reposition thermocouple in pilot flame. If it still won't keep pilot burning then replace thermocouple. Hope this helps. Thanks.

The pilot light will not stay lit. A new


Try cleaning the orfice for the pilot light. You will have to dis-assemble the fuel lines from the thermostat to the burner to get at it. The orfice has an extremly small hole in it, do not make it any larger, just clean it out.

Light pilot on Royal deep fryer. Pilot will not stay lit. Second fryer has larger pilot have no trouble keeping it lit. How can I adjust the pilot so that it will stay lit?


there is a small adjustment screw on the gas valve,turn it clockwise to increase pilot,if that does not work the vent cap on the gas regulator on the back of the unit could be stopped up,remove that cap ,clean out or replace unit can operate without it just fine.If you increase the pilot and it still wont stay lit replace the thermocouple

WE can get the pilot light lit but it will not stay on


You will need to check the pressure regulator for the gas.
It sounds like the gas pressure is to low to keep the pilot lit.

I don't know how to restart my old bosch water wizard 10p, pilot light has gone out.


get a long stick match, a flashlight remove lower inspection cover, find thermocouple and pilot light will be next to it,turn gas valve to pilot light and hold down,stick the match in by thermocouple till the pilot lights and hold valve down till pilot stays lit,this may take a minute or more,then release gas valve and see if pilot stays lit, if not retry,if it wont stay lit,the thermocouple is defective and needs replacement

Patio Heater pilot lights won't stay lit


crappy pilot flame (not properly heating the thermocouple), bad thermocouple, thermocouple loose where it screws into the pilot safety valve, bad safety valve magnet.

One or more of those is the problem.

Oh...there is also a saftey switch...in case it tips over. It will also cause the pilot to not stay lit (if the switch or wires that go to i are faulty)
